Primary care physician attitudes concerning follow-up of abnormal test results and ambulatory decision support systems.

OBJECTIVES: Failures to follow-up abnormal test results are common in ambulatory care. Information systems could assist providers with abnormal test result tracking, yet little is known about primary care providers attitudes toward outpatient decision support systems. METHODS: A cross-sectional survey of 216 primary care physicians (PCPs) that utilize a single electronic medical record (EMR) without computer-based clinical decision support. RESULTS: The overall response rate was 65% (140/216). Less than one-third of the respondents were satisfied with their current system to manage abnormal laboratory, radiographs, Pap smear, or mammograms results. Only 15% of providers were satisfied with their system to notify patients of abnormal results. Over 90% of respondents felt automated systems to track abnormal test results would be useful. Seventy-nine percent of our respondents believed that they could comply better with guidelines through electronic clinical reminders. CONCLUSIONS: Most PCPs were not satisfied with their methods for tracking abnormal results. Respondents believed that clinical decision support systems (CDSS) would be useful and could improve their ability to track abnormal results.

Primary care compensation at an academic medical center: a model for the mixed-payer environment.

The authors' academic medical center, Brigham and Women's Hospital, Boston, Massachusetts, developed a primary care physician (PCP) salary incentive program for employed academic physicians. This program, first implemented in 1999, was needed to meet the financial imperatives placed on the institution by managed care and the Balanced Budget Act of 1997; its goal was to create a set of incentives for PCPs that is consistent with the mission of the academic center and helps motivate and reward PCP's work. The program sought to simultaneously increase productivity while optimizing resource utilization in a mixed-payer environment. The salary incentive program uses work relative-value units (wRVUs) as the measure of productivity. In addition to productivity-derived base pay, bonus incentives are added for efficient medical management, quality of care, teaching, and seniority. The authors report that there was significant concern from several members of the physician staff before the plan was implemented; they felt that the institution's PCPs were already operating at maximum clinical capacity. However, after the first year of operation of this plan, there was an overall 20% increase in PCP productivity. Increases were observed in all PCP subgroups when stratified by professional experience, clinical time commitment, and practice location. The authors conclude that the program has succeeded in giving incentives for academic PCPs to achieve under the growing demands for revenue self-sufficiency, managed care performance, quality of care, and academic commitment.

Productivity, quality, and patient satisfaction: comparison of part-time and full-time primary care physicians.

CONTEXT: Although few data are available, many believe that part-time primary care physicians (PCPs) are less productive and provide lower quality care than full-time PCPs. Some insurers exclude part-time PCPs from their provider networks. OBJECTIVE: To compare productivity, quality of preventive care, patient satisfaction, and risk-adjusted resource utilization of part-time and full-time PCPs. DESIGN: Retrospective cohort study. SETTING: Boston. PARTICIPANTS: PCPs affiliated with 2 academic outpatient primary care networks. MEASUREMENTS: PCP productivity, patient satisfaction, resource utilization, and compliance with screening guidelines. RESULTS: Part-time PCP productivity was greater than that of full-time PCPs (2.1 work relative value units (RVUs)/bookable clinical hour versus 1.3 work RVUs/bookable clinical hour, P< .01). A similar proportion of part-time PCPs (80%) and full-time PCPs (75%) met targets for mammography, Pap smears, and cholesterol screening (P = .67). After adjusting for clinical case mix, practice location, gender, board certification status, and years in practice, resource utilization of part-time PCPs (138 dollars [95% confidence interval (CI), 108 dollars to 167 dollars]) was similar to that of full-time PCPs (139 dollars [95% CI, 108 dollars to 170 dollars], P = .92). Patient satisfaction was similar for part-time and full-time PCPs. CONCLUSIONS: In these academic primary care practices, rates of patient satisfaction, compliance with screening guidelines, and resource utilization were similar for part-time PCPs compared to full-time PCPs. Productivity per clinical hour was markedly higher for part-time PCPs. Despite study limitations, these data suggest that academic part-time PCPs are at least as efficient as full-time PCPs and that the quality of their work is similar.

Impact of poorly controlled hypertension on healthcare resource utilization and cost.

OBJECTIVE: To examine the relation between blood pressure (BP) control and utilization and cost of healthcare resources. STUDY DESIGN: A retrospective database study of managed care patients in New Mexico from January 1, 1996, to December 31, 1997. PATIENTS AND METHODS: We stratified 1000 hypertensive patients into categories based on average and maximum BP. Antihypertensive medication use and cost, number of physician visits, and interval between hypertension-related physician visits were determined. RESULTS: Medication costs increased progressively across all BP categories from lowest to highest, and higher average systolic BP (SBP) was significantly correlated with increased cost (P < .001). There were significant correlations between higher maximum BP and greater number of hypertension-related physician visits (P < .001). Mean number of visits for BP groups was 5.5 for patients with a maximum diastolic BP (DBP) < 85 mm Hg and 10.0 for those with a maximum DBP > or = 100 mm Hg (P < .001). Patients with a maximum SBP > or = 180 mm Hg averaged 9.7 visits, whereas those with a maximum SBP < 120 mm Hg averaged 4.1 visits (P < .001). Both SBP and DBP were significantly correlated with time to next visit (P < .001). Mean visit intervals ranged from 44 days for patients with an SBP < 85 mm Hg to 25 days for those with an SBP > or = 180 mm Hg (P < .001). A similar association was found between DBP and visit interval. CONCLUSIONS: Poor control of hypertension is associated with higher drug costs and more physician visits. Aggressive treatment might help reduce managed care costs and resource utilization.

Vaccination with a recombinant vaccinia vaccine containing the B7-1 co-stimulatory molecule causes no significant toxicity and enhances T cell-mediated cytotoxicity.

B7-1 is a co-stimulatory molecule that provides a second signal for T-cell activation. Several studies have demonstrated that vaccination with a vector containing genes encoding B7-1 and an antigen appears to be efficacious at promoting immune responsiveness to the antigen. To evaluate the safety of such a protocol and determine the effect of the B7-1 vector on immune responsiveness, female C57BL/6 mice were administered Wyeth wild-type vaccinia virus (V-WT) or V-WT containing the gene for B7-1 (rV-B7-1) as a single s. c. injection or 3 monthly s.c. injections. Immunologic parameters were evaluated in half of the mice and general toxicity in the other half. Immunologic end points included determination of splenic lymphocyte phenotypes, mitogen-induced T- and B-cell proliferation, T-cell proliferation in response to alloantigens, cell-mediated cytotoxicity (CMC), natural killer cell activity and serum anti-nuclear antibody (ANA) titers. No significant signs of general toxicity were noted. The primary immunologic effect was an increase in the ability of spleen cells to lyse allogeneic targets and to proliferate in response to allogeneic stimulation. Numbers of splenic CD8(+) cells were also increased. These effects were more pronounced after 3 vaccinations than after a single vaccination. Minimal differences in ANA were observed between mice immunized with V-WT and rV-B7-1. In addition, no serum antibodies against B7-1 were detected in any mice. The data suggest that vaccination with rV-B7-1 augments CMC with minimal toxicity.

Effect of case managers with a general medical patient population.

The objectives of this study were to evaluate the effect of inpatient case management (CM) on a general medical service and to determine if a prediction rule, identifying patients likely to need discharge planning services, could define a subset of patients for whom CM would be most effective. We hypothesized that CM would have greatest impact on patients predicted to be at highest risk of needing discharge planning to arrange for post-discharge medical services. We carried out a prospective controlled study. Six general medicine teams from a 600-bed urban teaching hospital were randomly assigned to CM (n = 4) or standard care (SC) (n = 2). Number of patients = 302 (207 CM; 95 SC). Case managers participated in daily physician team rounds and coordinated discharge planning for CM patients; SC patients received discharge planning from staff nurses or discharge planners when requested by physicians. The outcomes measured were deviation from the hospital length of stay (LOS) expected for a patient's diagnosis, patient satisfaction and non-acute medical service utilization during the month after discharge. Overall, patients from CM and SC teams did not differ in their deviation from expected LOS, post-discharge medical service utilization and patient satisfaction. However, after stratifying patients by their predicted need for post-discharge medical services, only patients in the 'high risk' category had a significantly shorter LOS under CM (2.9 days shorter than SC patients; P = 0.02). We concluded that, in this study, the effect of case managers on a general medical service was limited to shortening LOS only among a stratum of high risk patients.

Communication breakdown in the outpatient referral process.

OBJECTIVE: To evaluate primary care and specialist physicians' satisfaction with interphysician communication and to identify the major problems in the current referral process. DESIGN: Surveys were mailed to providers to determine satisfaction with the referral process; then patient-specific surveys were e-mailed to this group to obtain real-time referral information. SETTING: Academic tertiary care medical center. PARTICIPANTS: Attending-level primary care physicians (PCPs) and specialists. MEASUREMENTS AND MAIN RESULTS: The response rate for mail surveys for PCPs was 57% and for specialists was 51%. In the mail survey, 63% of PCPs and 35% of specialists were dissatisfied with the current referral process. Respondents felt that major problems with the current referral system were lack of timeliness of information and inadequate referral letter content. Information considered important by recipient groups was often not included in letters that were sent. The response rate for the referral specific e-mail surveys was 56% for PCPs and 53% for specialists. In this e-mail survey, 68% of specialists reported that they received no information from the PCP prior to specific referral visits, and 38% of these said that this information would have been helpful. In addition, four weeks after specific referral visits, 25% of PCPs had still not received any information from specialists. CONCLUSIONS: Substantial problems were present in the referral process. The major issues were physician dissatisfaction, lack of timeliness, and inadequate content of interphysician communication. Information obtained from the general survey and referral-specific survey was congruent. Efforts to improve the referral system could improve both physician satisfaction and quality of patient care.

When sick patients switch primary care physicians: the impact on AMCs participating in capitation.

Patients facing catastrophic illness often desire choice when selecting specialist physicians and will sometimes request specialists at academic medical centers (AMCs). Under capitated payment systems, community primary care physician (PCP) gatekeepers have an incentive to refer patients to local specialists with whom they regularly collaborate rather than to AMC specialists, who generally are more expensive and with whom they may not have working relationships. As a result of the financial pressures of capitation and the desire to work with familiar specialists, some PCPs in community-based risk-sharing groups are reluctant to refer sick patients in capitated health plans to AMC-affiliated specialists. Forced to choose between their existing primary care relationships and their desired specialists, some patients are terminating their existing primary care relationships to enroll with PCPs affiliated with the AMCs to which they wish to be referred. The authors' observations at their AMC indicate that most of the patients leaving their PCPs in the community do so to gain access to oncology and surgical specialty services. The shifting of sick patients in capitated health plans to AMC-affiliated PCPs creates a financial burden for both AMCs and their affiliated physicians. Health plans and AMCs must cooperate in developing a solution; for example, risk-adjust each risk unit's capitation payment based on the health status and disease burden of its population. The authors propose strategies aimed at enabling patients to have access to AMC tertiary care services while ensuring that the cost of caring for the sickest patients is not borne solely by AMC risk groups. They conclude that it is in the best interests of all concerned to modify the current counterproductive incentives that promote the problems they have described.

Does a year make a difference? Changes in physician satisfaction and perception in an increasingly capitated environment.

BACKGROUND: Although capitation has become an increasingly common method of payment for heath care, little is known about changes in physician satisfaction as they become more experienced working in a capitated environment. METHODS: We surveyed the members of a physician hospital organization at an urban teaching hospital in the summers of 1996 and 1997. In 1996, fully capitated contracts covered <5% of patients under 65 years of age, but that figure increased to nearly 25% by 1997. We assessed physicians' satisfaction with their practice, compared satisfaction under fee-for-service and capitated payment, and evaluated ethical issues related to capitation. RESULTS: In 1996, we surveyed 587 physicians with direct patient care responsibilities, of whom 62% responded; 51% of 520 physicians responded in 1997. Overall satisfaction was 57% in 1996 and 71% in 1997. Among physicians who responded in both years, overall satisfaction was unchanged, but increases in satisfaction were noted for patient load (an increase of 0.5 points on a five-point scale, P <0.01), time to discuss patient needs (an increase of 0.3 points, P <0.01), and helpfulness of care coordination (an increase of 0.5 points, P = 0.02). In a direct comparison between fee-for-service and capitation, physicians were more satisfied with both methods of payment in 1997 than they were in 1996, but they were much more satisfied with fee-for-service in both years. For many individual indicators, the difference in satisfaction between fee-for-service and capitation increased between 1996 and 1997. CONCLUSION: When introduced to capitation, physicians had strong negative perceptions about it. After a year's experience, satisfaction with capitation improved, but perceived differences between capitation and fee-for-service grew even larger. Thus, physicians have serious concerns about capitation that may not be alleviated by experience with it.

A computer-based outpatient clinical referral system.

The process of generating a clinical referral for a patient, and the resulting transfer of information from the primary care physician to the specialist and back again, are key components in the struggle to deliver less costly and more effective clinical care. We have created a computer-based, outpatient clinical referral application that facilitates: (1) identifying an appropriate specialist; (2) collecting the clinical, demographic, and financial data required to generate a referral; and (3) transferring the information between the specialist and the primary care physician (PCP). This article describes the development of the application itself and several of the knowledge bases that were created to facilitate this process. Preliminary results indicate that the new computer-based referral process is faster to use than conventional methods.

PHOs and risk: aligning incentives with internal subcapitation.

Many PHOs have not realized the efficiencies they anticipated when they accepted capitation payments on behalf of their member organizations. Internal subcapitation of professional and facility expenses can promote the organizational alignment of incentives necessary for PHOs to succeed in competitive managed care markets. PHOs may establish subcapitation budgets and corresponding leakage pools to augment efficiency and promote patient access within the PHO. Care should be taken, however, that sufficient resources needed to collect and analyze utilization data, as well as the infrastructure needed to administer subcapitation, are in place.

Realizing the financial benefits of capitation arbitrage.

By anticipating the arbitrage potential of cash flow under budgeted capitation, healthcare organizations can make the best use of cash flow as a revenue-generating resource. Factors that determine the magnitude of the benefits for providers and insurers include settlement interval, withhold amount, which party controls the withhold, and incurred-but-not-reported expenses. In choosing how to structure these factors in their contract negotiations, providers and insurers should carefully assess whether capitation surpluses or deficits can be expected from the provider. In both instances, the recipient and magnitude of capitation arbitrage benefits are dictated largely by the performance of the provider.

A prediction rule for the use of postdischarge medical services.

OBJECTIVE: To develop and validate a prediction rule screening instrument, easily incorporated into the routine hospital admission assessment, that could facilitate discharge planning by identifying patients at the time of admission who are most likely to need postdischarge medical services. DESIGN: Prospective cohort study with separate phases for prediction rule development and validation. SETTING: Urban teaching hospital. PATIENTS/PARTICIPANTS: General medical service patients, 381 in the derivation phase and 323 in the validation phase, who provided self-reported medical history, health status, and demographic data as a part of their admission nursing assessment, and were subsequently discharged alive. MEASUREMENTS AND MAIN RESULTS: Use of postdischarge medical services such as visiting nurse or physical therapy, medical equipment, or placement in a rehabilitation or long-term care facility was determined. A prediction rule based on a patient's age and Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) physical function and social function scores stratified patients with regard to their risk of using postdischarge medical services. In the validation set, the rate of actual postdischarge medical service use was 15% (15 of 97), 36% (39 of 107), and 58% (57 of 98) among patients characterized by the prediction rule as being at "low", "intermediate," and "high" risk of using postdischarge medical services, respectively. CONCLUSIONS: This prediction rule stratified general medical patients with regard to their likelihood of needing discharge planning to arrange for postdischarge medical services. Further research is necessary to determine whether prospective identification of patients likely to need discharge planning will make the hospital discharge planning process more efficient.

Prevalence of adult domestic violence among women seeking routine care in a Native American health care facility.

OBJECTIVES: The purpose of this study was to determine the prevalence of, and sociodemographic factors associated with, adult domestic violence within a Native American community. METHODS: Adult women in the community were surveyed. RESULTS: Of 371 eligible women, 341 (92%) were surveyed. Among respondents, 179 reported a history of at least 1 episode of domestic violence. Fifty-six (16.4%) reported violence within the previous 12 months. Age under 40 years and living in a household receiving governmental financial assistance were independently associated with 1-year prevalence of adult domestic violence. CONCLUSIONS: Adult domestic violence is prevalent within this Native American community. Additional research is required to characterize further the relationship between domestic violence and socioeconomic status.

Acute and subchronic toxicity studies with detirelix, a luteinizing hormone-releasing hormone antagonist, in the rat and monkey.

Acute (single dose), 2-week, and 3-month toxicology studies were conducted with detirelix, a luteinizing hormone-releasing hormone (LHRH) antagonist, in rats and cynomolgus monkeys. Acute studies were conducted by intravenous and subcutaneous injection. Subchronic studies were conducted by daily subcutaneous injection. Clinical signs after a single intravenous dose included lethargy, edema, cyanosis, pallor, and red ears in rats at greater than or equal to 0.3 mg/kg and lethargy and facial flushing in monkeys at greater than or equal to 0.5 mg/kg. In subchronic studies, detirelix at greater than or equal to 0.4 mg/kg/day (rats) and at greater than or equal to 0.2 mg/kg/day (monkeys) produced atrophy of the reproductive organs, inhibition of ovulation and spermatogenesis, decreased body weight gain in male rats and monkeys, and increased body weight gain in female rats. In the rat, morbidity and/or mortality occurred throughout the treatment phase at a subcutaneous dose of greater than or equal to 2.0 mg/kg/day. In both species, the time to recovery of normal reproductive organ morphology and function was directly related to dose. Exogenous testosterone decreased the severity of reproductive and body weight effects in male rats. In conclusion, the acute effects of detirelix were consistent with peripheral vasodilation. Subchronic effects were associated with inhibition of pituitary gonadotropic and gonadal hormone secretion.
